Children perform worse than adults on tests of cognitive flexibility, which is a component of executive function. To assess what aspects of a cognitive flexibility task (cued switching) children have difficulty with, investigators tested where eye gaze diverged over age. Eye-tracking was used as a proxy for attention during the preparatory period…

Provides a theoretical account of children's success on theory of mind (ToM) tasks and the discrepancies found across different ToM tasks, and examines the role of indexical and symbolic referencing. Found that 4- to 6-year-olds succeeded more on tasks with a high ratio of indexical to symbolic references than on tasks with a high ratio of…

Distinguishes two types of executive theories: (1) emergence accounts; and (2) expression accounts. Asserts that the meta-analytic findings reported by Wellman, Cross, and Watson (2001) are fully consistent with emergence accounts of theory of mind and do not entirely rule out expression accounts.

Kim (1985) found that both English-speaking and Korean-speaking children find true negative sentences more difficult to verify than false negative sentences. A closer examination of the findings reveals that the difficulty is greater among Korean-speaking children. (Author/RH)

Replies to Akiyama's critique, pointing out areas of agreement between the Kim and Akiyama studies and areas of disagreement. Concludes that, contrary to Akiyama's argument, the Kim (1985) data would not directly challenge the cognition primacy hypothesis in any serious manner. (RH)

Three studies investigated how experiencing nearby locations together in time influenced memory for location in 7-, 9-, and 11- year-olds and adults. Findings suggested that experiencing nearby locations together in time increased the weight children assigned to categorical information in their later estimates of location. Results were similar…

Examined the relationship between 6- to 8-year olds' conceptual understanding of additive composition, commutativity, and associativity principles and addition problem-solving procedures. Results revealed that conceptual understanding was related to using order-indifferent, decomposition, and retrieval strategies and speed and accuracy in solving…

There is a change in false belief task performance across the 3-5 year age range, as confirmed in a recent meta-analysis [Wellman, H. M., Cross, D., & Watson, J. (2001). Meta-analysis of theory mind development: The truth about false-belief. "Child Development," 72, 655-684]. This meta-analysis identified several performance factors influencing…

Results obtained from 44 children (ages 7 through 16) with sex chromosome abnormalities and from 17 chromosomally normal siblings demonstrated that children in the former group have an increased risk of encountering learning problems. (MP)

To assess children's understanding of intentions as distinct from desires, this study presented 3- to 7-year-olds and adults with situations in which intentions were satisfied but desires were not, or vice versa, in a story-comprehension task and target-hitting game. Findings indicated that younger children were unable to differentiate desires and…

Investigated children's representational ability as a cognitive factor underlying the suggestibility of their eyewitness memory. Found that the eyewitness memory of children lacking multirepresentational abilities or sufficient general memory abilities (most 3- and 4-year-olds) was less accurate than eyewitness memory of those with…

Investigated whether Brazilian 4-year-olds held essentialist beliefs about animal categories. Found that middle class and poor children were equally likely to interpret labels as referring to mutually exclusive animal categories, and more likely to accept a common label for animals sharing internal properties than superficial properties,…

Concludes that strategies are not responsible for memory span development in children 7 through 13 years old. Running and fixed memory span tasks and a running probe task were administered to 38 children. The probe task showed age differences as great as with the fixed span task. Span was reduced by approximately half an item over all ages.…

Finds that the usual adult superiority in speed of processing could be markedly reduced if children were given equivalent amounts of domain knowledge. The effect was domain specific; differences in knowledge affected processing rates in both knowledgeable adults and children to about the same extent. (Auther/RH)

Seven- and eight-year-old children were given two memory trials on each of five consecutive days. Results indicate that children who were given only demonstrations and directions to use particular mnemonic strategies did not perform as well as children who were provided explanations and feedback regarding the mnemonic value of these actions.
